sooo...i'm stoked

i have been riding around on a pretty old hyperlite board for a while now. secretly i have been wanting to try out a ronix one board or a slingshot. well my dad calls me today and he bombards me with wakeboard questions without even explaining what he is talking about. he asked me what my boot size was and if i like open or closed toe. which i said open (which i will get to later)... then he says "well i'm working out a deal and i'm trying to get us a ronix one board. what are the odds. i never even told him i wanted to try that board out. so i'm going to contact the guy later and tell him exactly what i want. but i just wanted to know what are the advantages and disadvantes of open and closed toe. i've always rode open but dont know a thing about closed. and they asked what kind of binding (which i dont know where to start). i've only heard that the ronix one bindings literally stink. and what kind of lining. (hard or soft) (or white or gold) or something like that. i dont know what that means. so any advice would be much appreciated
